http://snamigos.blogspot.com/2017/11/how-to-get-changed-or-modified-fields.html

where the blogger is recommending this approach:

//this will give you array of changed field names
var changed _fields = getChangedFieldNames(current);

function getChangedFieldNames(gr) {
 
var result = [];
var elements = gr.getElements();
var size = elements.length;
for (var i = 0; i  < size; i++) {
var ge = elements[i];
if (ge.changes()) {
result.push(ge.getName());
}
}
 
return result;
}
